Good metal band that uses 7 strings or plays in drop a?

After the Burials first album (Forging a Future Self) uses 7 strings, you might be hard pressed to find tabs for there older stuff but if you are good at picking things up by ear you can fairly easily do it. Make sure you get Forging a Future Self though, because there newest Rareform, which is amazing I must say, but they use 8 strings on it so ya.
